\VILLTAM SGHULTE, OF APOLLO, ASSIGNOR OF THREE-EIGHTHS TO ROBERT D. SOHULTE, OF PITTSBURG, PENNSYLVANIA.

APPARATUS FOR REMOVING FRICTIONAL ELECl'RlCiTY FROM MACHINERY.

SPECIFICATION forming part of Letters Patent No. 393,125, dated November 20,1888.

Application filed June13, 1887.

To aZZ whom it may concern:

Be it known that I,\VILLIAM SoHULTE,a citizen of the United States, residing at Apollo, in the county of Armstrong and State of Pennsylvania,haveinvented a certain new and useful Appliance for Removing or Conducting Away Frictional Electricity ot'Machinery; and I. do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing. which forms a part of this specification. Theatoresaid drawing shows my invention as applied to a rolling-mill plant.

The invention consists in electrical conductors applied to the constituent members of a plant of machinery and arranged in as many circuits as there are individual members of the plant, combined with a switch-board and ground-conueetions for both the machinery and the electrical conductors, as will appear more fully hereinafter and as claimed.

In the drawing, A may represent a steam pumping-engine drawing its water through feed-pipe 1,which is clectricallygrounded in a source of supply, and B may represent a battery of steam-boilers supplied with water from said pumping-engine, and connected by an insulated wire, 2, to the switch-hoard G, thence to the electrical bell H, (which may be a signal, alarm, or other mechanism adapted to be moved by the electricity collected from the machinery,) thence to a galvanometer, I, and

thence to groundsay in a running stream.

The rolls 0 G are connected separately with the switch-board by means of insulated wires 3 Serial Noflllfl-Zl. (No model.)

and ethaving spring-contacts M M,arranged at the dead-centers of the lower rolls. These spring-contacts may be packed with rubber 0 and clamped to wooden blocks. The shafting F is connected to the switch-board by a wire, 5, which terminates in a springcontact, D, similar in construction and arrangement to the contacts M.

It will be observed that the feed-water pipe 1 and the grounded wire 2 complete the circuit, and that anyone or all of the wires 2, 3, 4, and 5 may be in servicean d that the switchboard admits of the cutting out of any of the wires at pleasure.

Instead of the bell and galvauometer,other apparatus capable of being operated by the current obtained might be substituted.

I have found that the current generated es- 5 pecially by moving machinery was proportionate to the work performechand the heavier the work the stronger the current. The useful purposes therefore to which the thus-collected electricity may be put are limited only by the characteristics of the current.

XVhat I claim is An appliance for ren'ioving or conducting away frictional electricity generated in or by a plant of machinery, consisting of electrical conductors arranged in as many circuits as there are individual members of the plant, c0mbined with a switch-board and ground-connections for both the machinery and the electrical conductors, substantially as described.

\VILLIAM SOHULIE.
